An ARDS treatment that involves a slow, continuous rotation of the bed to less than 40 degrees to mobilize secretions and provide postural drainage.

_________ failure occurs when blood exits the heart without participating in gas exchange.

Shunt

What interventions can help manage excess lung secretions that can result in hypoventilation? (4)

Turning every 1 to 2 hours, chest physiotherapy to lung areas with high secretions, encourage deep breathing and coughing, and suctioning.

What is permissive hypercapnia in relation to ARDS?

The elevation in PaCO2 that occurs from using smaller tidal volumes (6 mL/kg) and varying PEEP

How does increased intrathoracic pressure from hyperventilation (a common complication of ARDS-related ventilatory treatment) impact the heart and cardiac output?

It increases the right ventricle's afterload which limits blood flow from the right side of the heart to the left side of the heart. This decreases cardiac output which decreases blood return to the right side of the heart.

What technique increases SaO2 by slowing respirations, allowing prolonged expiration and preventing small bronchioles from collapsing?
